QISTA-Net: DNN Architecture to Solve ${\ell }_q$-norm Minimization Problem and Image Compressed Sensing

Gang-Xuan Lin, Shih-Wei Hu, Chun-Shien Lu

In this paper, we reformulate the non-convex ${\ell }_q$-norm minimization problem with $q\in (0,1)$ into a 2-step problem, which consists of one convex and one non-convex subproblems,…
